Consider a function $f: R \to R$ f: R \to R, f(x) = 2x+8.

Determine the correct sequence to prove the following statement.

f is injective.

If a statement is not used in the proof, you have to choose "Not used".

Assume f(x)=y.

Assume that f(a)=f(b).

$x = \frac{y-8}{2}$ x = \frac{y-8}{2} exists

Consider two arbitrary real numbers a and b.

2x+8=y

f is injective

Consider an arbitrary real number y.

f is surjective

a = b

2a+8=2b+8
